Daikin VRV II Addressing

[Damoburn]

I am looking for a technical manual for addressing the indoor units on a Daikin VRV II system.

I have a single outdoor unit (REYQ8PY1B) with seven indoor cassette units. Each has a BRC1D52 remote control attached.

I am attaching attaching a Modbus Interface adapter which I have done a few times before, but on all the other systems they had the old remote control. The button configuration is different and cannot get to save new address.

Hi Damoburn
I know that to address the systems using BRC1D52 controllers you need to press and hold the test button. You should have a 00 displayed. If you have 01 instead then your system cant see a central control device.
I have used a Bacnet gateway, and an i-controller but not a Modbus. Is this a control device, or just an enable/fault interface?
